Ummm...The FM2 v. Spit16 thing is actually a terrible example. This is because, the FM2 turns tighter, and the average pilot, especially if he is exclusively a Spit man, knows little of E fighting and mainly fights by hauling back on the stick. So the FM2 can actually be a typical Spit16 pilot's worst nightmare, it will tend to get on his six and stay there unless the Spit guy runs.
It is NOT an amazing feat of pilot whoop-de-doo to win a turnfight with an EW bird against a LW one, IF that EW bird happens to have a miniscule turn radius compared to whatever LW brick it is fighting.
